Your DOMETIC HEKI window mosquito net is probably broken and the strings are hanging, so you can't close the blinds properly or fall asleep normally because it's 'lit'... And as is typical in the world of caravanning, you probably think it will be expensive. It won't, you can repair your roller blind for pennies and it will serve you for years again. The set contains 4 pieces - just in case all 4 hooks are broken. Or you will simply need this set in the future when the factory hooks finally fail,)
Difficulty level of repair? Super simple. You remove the mosquito net frame, attach a hook for a droplet or some mammoth, install the roller blind and sleep soundly again.
The product is made of PETG material, which means it will work for a long time.
